BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint of floor panels used for forming a floor such as a balcony or a terrace.

[0002]

2. Description of the Related Art Generally, floors such as balconies and terraces are formed by assembling foundations such as joists and then laying existing floor panels produced in a factory on the joists. If a large floor panel is required, a large floor panel corresponding to the floor requires a large number of personnel for transportation and laying work.

[0003] If a large floor area is required,
Small unitized floor panels are joined on site. By the way, as shown in FIG. 3, a joint portion of a conventional floor panel is formed by joining a joining wall 102 provided at an end portion of a floor panel 101 via a sealing material 103 and a bolt 104.
Water is prevented from leaking from the joint by tightening the nut and the nut 105. However, in such a structure of the joint, when the bolt and the nut are unfastened, the floor panel 101 is unfastened.
When the bolts 104 and nuts 105 are not properly tightened due to inexperienced workers, water leakage from the joint to the downstairs may occur. There is a risk of doing so.

In order to solve such a problem, a structure of a joint portion of a floor panel has been proposed as disclosed in Japanese Utility Model Publication No. 3-22970. As shown in FIG. 4, the joints of the floor panels are formed by joining the joint walls 107 of the adjacent floor panels 106 via the sealing material 108 and sandwiching the joint wall 107 facing each other with the clip-shaped fastener 109. Since the joint structure is used, bolts, nuts and tools are not required for joining, and it is not necessary to raise and work the floor panel 106 when assembling or disassembling the floor panel 106, and workability is improved. The construction is simple and quick, and has an excellent advantage that even an unskilled worker can form a reliable watertight structure.

[0005]

However, in the structure of the joint shown in FIG. 4, the joint wall 107 and the joint wall 107 must be joined so as to be in close contact with each other via the sealing material 108. Subtle width adjustments cannot be made by simply combining floor panels. Therefore, in order to form various floors having different sizes, it is necessary to prepare a large number of floor panels having different width dimensions.
Building costs are very high.

In view of such circumstances, the present invention eliminates the need for bolts, nuts and tools for joining, and eliminates the need to raise and work the floor panel when assembling the floor panel, thereby improving workability. At the same time, it provides a joint for floor panels that can be easily and quickly constructed and that even an inexperienced worker can have a reliable watertight structure and can easily adjust in the width direction. It is intended to be.

[0007]

In order to achieve such an object, the joint of the floor panels according to the present invention is such that the first floor panel has a lower height than the first wall and the first wall. A first groove portion provided so as to face the second wall with a bottom of a predetermined width therebetween is formed integrally with the floor panel main body so that the first wall hangs down from an edge of the floor panel main body. The floor panel has a second groove portion provided with a first wall and a second wall having a height lower than the first wall facing each other across a bottom having a width smaller than the bottom of the first groove portion.
The first wall is integrally formed with the floor panel main body so as to hang down from an edge of the floor panel main body, and the two floor panels are configured so that the second groove of the second floor panel is formed by the first floor panel. The seal tape is arranged side by side so as to face the inside of the first groove, and one end edge in the width direction is attached to the inner wall surface of the first wall of the first groove.
The other end is adhered to the inner wall surface of the second wall of the second groove, and the gap between the first wall of the first groove and the second wall of the second groove is watertightly closed from above. .

In the above configuration, it is preferable that a gap formed by the first wall of the first groove and the first wall of the second groove is closed by covering the lid. In addition, it is preferable that a protrusion such as a ridge facing the gap is provided on the back surface of the lid so as to prevent the lid from shifting in the lateral direction and falling into the gap. It is preferable that the sealing tape has flexibility as much as possible. Also, a tape in which an adhesive layer is provided in advance on the entire surface of the sticking surface may be used, or an adhesive may be applied when sticking to a portion to be stuck to the first wall or the second wall. I do not care.

In the case where three or more floor panels are connected continuously, floor panels other than the floor panels at both ends are provided with either a first groove or a second groove at both ends.

[0010]

According to the above arrangement, first, the first floor panel is arranged at a predetermined position on the joist. Next, the second floor panel is placed on the joist with the groove facing the first groove of the first floor panel, and is shifted in the horizontal direction as required, and then fixed at a predetermined position. That is, since the width of the bottom of the first groove of the first floor panel is wider than the width of the bottom of the second groove of the second floor panel,
The second floor panel freely moves in the horizontal direction by the difference in the width, and the floor width can be adjusted.

Then, one end in the width direction of the seal tape is attached to the inner wall surface of the first wall of the first floor panel, and the other end is attached to the inner wall surface of the second wall of the second floor panel. The gap between the first wall of the first floor panel and the second wall of the second floor panel is covered from above, so that rainwater or the like does not enter the groove of the first floor panel from the gap. Further, it is preferable that a gap formed between the first walls of both floor panels is covered with a lid from above.
